Router/ Switch Operating System POS 355 2013 Router/ Switch Operating System Cisco IOS or Inter-work Operating System is an operating system for the company Cisco’s system routers and network switches. Cisco systems is a multinational corporation based in San Jose of California that designs‚ manufactures‚ and sells networking equipment. The company was founded in 1984 by two people working at Stanford University on the computer support staff. The two Stanford University members were

standards and protocols‚ we would have a harder time making devices that we use every day to inter-operate. Imagine buying specific BRAND of ROUTER for a SPECIFIC computer just to use the internet; so if you have a Sony computer you would also need a Sony wireless router to connect to the internet via provided Sony made routers. We would to have multiple routers depending on the devices we own and probably would not be able to use internet when we’re in a café‚ library‚ or airport because of incompatibility

switches have essentially replaced repeating hubs in business environments. A conceptual software-driven special application of LAN switches‚ called Virtual LANs (VLANs)‚ was introduced in the mid-nineties with a lot of hype. They promised cost effective router-like benefits with the added advantage of reduced system administration costs. As we approached and then entered into the 21st century‚ other technological advances challenged the VLAN‚ and ultimately displaced it. This paper will builds the case

A local area network (LAN) is a computer network that interconnects computers in a limited area such as a home‚ school‚ computer laboratory‚ or office building using network media.[1] The defining characteristics of LANs‚ in contrast to wide area networks (WANs)‚ include their smaller geographic area‚ and non-inclusion of leased telecommunication lines. ARCNET‚ Token Ring and other technology standards have been used in the past‚ but Ethernet over twisted pair cabling‚ and Wi-Fi are the two most
